Lock 25 is one of seven 1,200-foot lock chambers authorized by the program and the first to be funded for construction. Lock 25 received $732M to fund design and construction of the project.
The project scope includes a new 1,200-foot lock chamber adjacent to the existing 600’ chamber and upstream/downstream approach walls. When complete, the new lock will improve the efficiency and reliability along with adding redundancy at Lock 25. Reference image below for general project layout.
